我正在开发一个需要在运行时加载动态模块的Django应用程序。现在,我能够上传(从客户端浏览器到服务器)“插件”并在数据库中注册插件模型等。但是我需要一种处理每个插件的urlpatterns的方法。目前,我已经在webapp的“核心”中编写了一个函数,该函数注册一个模型并(理论上)通过包含它将上传的插件的urlpatterns添加到webapp urls.py中。这个函数是:
def register_plugin_model(model,codename):
# Standard syncdb expects models to be in reliable locations,
# so dynamic models need to bypass django.core.management.syncdb.
# On the plus side, this allows individual models to be installed
# without installing the entire project structure.
# On the other hand, this means that things like relationships and
# indexes will have to be handled manually.
# This installs only the basic table definition.
if model is not None:
style = color.no_style()
cursor = connection.cursor()
tables = connection.introspection.table_names()
seen_models = connection.introspection.installed_models(tables)
statements,trsh = connection.creation.sql_create_model(model, style, seen_models)
for sql in statements:
cursor.execute(sql)
# add urlpatterns
from django.conf.urls.defaults import patterns, url,include
from project.plugins.urls import urlpatterns
urlpatterns += patterns(url(r'^' + codename + '/' , include ( 'media.plugins.' + codename + '.urls' )))
插件以tgz格式上传到“media/tmp”,然后解压到“media/plugins/”,其中插件的代号是插件名称。用户上传的插件由“project.plugins”管理。
所有插件逻辑都正常工作,但是当我尝试将上传的插件urls.py文件包含到Web应用中(project.plugins.urls)时,它没有任何效果。我已经打印了“project.plugins.urls.urlpatterns”的值,发现在进行“urlpatterns += pat....”操作后,该值未被修改。
有没有办法实现我需要的功能呢?
此致
敬礼
